Thank you to Mike Dimmick for info on Pick TV.
Got to warn you Mike, I studied Latin for 5 years and I was no good at it either, so I might be back for more help! Cheers as the Romans should have said.

I receive first class reception with freeview through my TV set.My question is why can I only get a few freeview channels?
Is there something I can attach to the tv or something I can do to the tv to solve this problem.
thanking you in anticipationW

James: Probably because you have a group A aerial and not a wideband one.
When DSO is comple a group A aerial should be fine for Divis.
Which channels are missing ?
